How the lung handles drugs: pharmacokinetics and pharmacodynamics of inhaled corticosteroids.
نویسندگان
چکیده
Bronchial asthma and allergic rhinitis are among the most common diseases of modern society and to an increasing degree a major cause of illness, hospitalization, loss of productivity, and death. Despite improvements in drug therapy over the years, the incidence is still increasing. Inhaled and intranasal corticosteroids are the drugs of choice in the therapy of asthma and allergic rhinitis. Inhalation and intranasal use result in better, target-specific delivery of corticosteroids. Higher concentrations at the site of action and minimized systemic exposure provide improved therapeutic ratios. However, there is still considerable concern over the risk of systemic side effects. It is the goal of inhaled and intranasal corticosteroid therapy to produce long-lasting therapeutic effects at the site of action and minimize systemic side effects with high clearance, low oral bioavailability and high plasma protein binding. This article reviews the pharmacokinetic and pharmacodynamic properties of corticosteroids used in asthma and allergic rhinitis.

The fate of inhaled drugs: the pharmacokinetics and pharmacodynamics of drugs administered by aerosol.
Prior to a drug achieving its effects (ie, pharmacodynamics), there are numerous events within the body that determine its ultimate fate. The effects of the "body on the drug" has been referred to as pharmacokinetics-how the favorable lung-to-systemic effects predicted from this exercise translate into practice. Inhaled drugs have enjoyed the major feature of having "local" effects on the targe...

1. A high therapeutic ratio for the inhaled route of administration is achieved by delivering doses which achieve a high local concentration in the lung and relatively low levels of systemic absorption. 2. Pharmacokinetic evaluation of drug absorption from the lungs provides an accurate and reproducible method for comparing different inhaler delivery systems, as well as for evaluating bioequiva...

متن کاملRelevance of pharmacokinetics and pharmacodynamics of inhaled corticosteroids to asthma.
The pharmacokinetic and pharmacodynamic effects of inhaled corticosteroids (ICS) have shaped the efficacy and safety of these agents in the treatment of asthma. Important pharmacokinetic and pharmacodynamic characteristics that can enhance the efficacy of ICS include small particle size, high glucocorticoid-receptor-binding affinity, long pulmonary residence time and lipid conjugation. These ch...
